Amongst the powers bestowed upon the Four Horsemen, the most devastating is their ability to take on large and very powerful forms for brief periods of time. The particulars of the transformation differ between the Horsemen. Only War and Death's transformations have been revealed.

Chaos Form is War's most powerful ability in Darksiders. It has the appearance of a hulking fiery demon far larger than War's normal form with vestigial wings on its back and a sword of fire in its hand.

– Samael on War's Chaos Form
War's Chaos Form is utilized by way of War building the Chaos energy necessary to transform through successful melee attacks. Once a certain amount of energy is obtained, War is able to trigger the transformation at will. Sustaining the transformation rapidly drains War of Chaos energy, and when the Chaos Gauge is empty, War reverts back to his typical humanoid state. When War is in Chaos Form he is invulnerable and inflicts massive damage; even a Trauma will die in five strikes. War is also able to slam his sword onto the ground in front of him to perform an area of effect attack that damages all foes near the strike. Besides powerful enemies like one of the The Chosen, there are few capable of surviving a meeting with War's Chaos form. However, War is not able to use any of his other weapons, abilities, or Wrath powers for the duration of his transformation. Once triggered, the transformation cannot be prematurely deactivated. Chaoseater provides the greatest amount of Chaos energy per hit of all War's weapons in-game. Interestingly, during War's fight with Abaddon, during which he wields the Armageddon Blade rather than Chaoseater, any attempt to use Chaos Form results in it being immediately deactivated.
War unleashes this power during the Apocalypse in the game's prologue while battling a Trauma. Angels flying overhead instantly recognizing the fiery entity below them. When the Tormented Gate rises to retreat a horn sounding can be heard, a similar to that of an Earthcaller. All at once, War is drained of his power, unable to sustain his Chaos Form. Later after killing Tiamat, Samael tells him to tap into his inner rage by striking down The Watcher, giving him back his Chaos Form.
Reaper FormEditReaper Form is Death's more powerful form, similar to War's Chaos Form. Once transformed, Death takes on a larger skeletal form. His face is completely hidden in the shadows of a cowl, a large robe envelopes the rest of his body, and skeletal wings sprout from his back. He hovers slighty above the ground when fighting on the ground, and is able to use this ability to fly. While transformed, he wields a massive scythe with many skulls engraved into the flat of the blade.
Death can partially tap into his Reaper Form at the end of many of his attack sequences without using any reaper energy. The partial utilization manifests itself as a semi-opaque energy construct in the shape of Death's Reaper form that briefly surrounds him at the end of the aforementioned attack sequences.
Death, like War, is able to acquire the energy required for a full transformation by striking enemies with his weapons. However, only his scythe attacks serve to build this energy; secondary weapons will not serve this purpose without the use of a special talisman. While in this form he is not quite invulnerable but the damage he takes is almost entirely mitigated. He deals massive amounts of damage with his scythe, allowing him to easily tear through large groups of weak enemies or go toe to toe with tougher monsters. He is also able to telekinetically control the movements of his scythe, using it, in one instance, to remotely carve up the innards of a monster known as Karkinos. In this form, he is able to teleport short distances and fire purple energy projectiles from his scythe. While he cannot use any of his Wrath powers or other abilities while in Reaper form, the form itself does not affect the status of abilities used just prior to transforming. As such, he can still benefit from magics such as the power boosts and electrical discharges of his Aegis Guard ability. Additionally, offensive "fire and forget" magics such as Frenzy, Murder or Exhume that were used just prior to transforming are not canceled, and function as they normally would while Death's Reaper form is engaged. Death is able to end his transformations at will, allowing him to conserve reaper energy should his enemies be destroyed before the transformation's time limit expires. Death is also seen using his transformation in many fairly casual situations, often transforming in order to take advantage of his Reaper form's ability to fly.
Death is able to access Reaper Form after gaining the first few levels of combat experience on his journey to revive humanity, though it can grow more powerful through further experience. He frequently used it to finish off particularly powerful foes.
- Using the Grim Talisman allows Death to gain reaper energy with both his primary and secondary weapons, and significantly boosts the amount of reaper energy obtained from scythe attacks.
- Level 5: Unlocks Reaper Form
- Level 10: Unlocks Reaper Counter
- Level 15: Increases strength and duration of Reaper Form
- Even though it is categorized in the game as a passive ability it is a very special passive ability. War's form can't be used at any time since it needs the Chaos level completely full, and is temporary once activated.
- Chaos form's in-game model is a variant of the Fallen, minus the club on its tail and has smaller deformed or vestigial wings. It also wields an added flaming sword.
- The Reaper Form is initially weaker than War´s Chaos Form, dealing less damage with a shorter duration and Death can still get damaged by tougher enemies. However, when Death reaches level 15, the duration and strength of Reaper Form increases to the same extent of War's Chaos Form.
- Death's Reaper Form grants him an appearance similar to the common depiction of the Grim Reaper.
